Reading minds is a bit of a tricky issue in my opinion. Our minds are powerful things and so the mind which is doing the reading has to be as powerful (at least) or more powerful than the mind being read. Ortherwise, there could be problems.
I know some people are not ready to read minds because "they can't handle the truth"; it is quite obvious simply from many comments which I receive. Also, You can see that from other people's answers to your question here: people fear each other still ... and themselves. They talk about riots and hurting others ... The will must be stronger than that.
So to answer your question, if we all had enough will-power to be who we really are then, reading minds would actually become "normal" (I so dislike that word but I can;t find another at the moment ...) but we're not fully there yet. The time will come though, when we we all find our way.
Thank You for the great question Mr. O'Brian and it's good to see You. I was thinking of You and "your" ravens just the other day. May Wakan Tanka walk with You.
